/* Possible task setup:
-> Supervisor: Monitors mainly which state the system should be in, starts/stops Manual/ARC/HARC tasks
-> Manual: Simply passes servo inputs to servo outputs, maybe some logging too
-> ARC: Assisted RC, fancy name for stabilisation only (aka. Auto1)
-> HARC: Higly Assisted RC, fancy name for full autonomous (aka. Auto2)
-> GPS: Simply parses incomming GPS data and puts it into the GPS struct, also set states of FIX/NOFIX etc.
-> Gatekeepers: Tasks which use queue's to access shared resources
-> MicroSD: Simply logs data to the MicroSD card
-> Telemetry: Sends telemetry using a queue
- Supervisor should have highest possibly priority (Idle + 14) We only have 5 task levels, as long as it yeilds that is fine.
- Supervisor should also act as the warnings system, low batter etc)
- Supervisor should handle all telemetry inputs (not outputs), and act accordingly
- ARC and HARC tasks should be split into two parts, gathering sensor data and acting on sensor data.
- Sub tasks of the supervisor should have a priority just lower than the supervisor (Idle + 12?)
- Sub tasks of the supervisor shoud ONLY be pre-empted by system interrupts such as UART, I2C etc
- Gatekeepers should sit in a blocked state while there is nothing on the que, with a low priority
- With the low priority of gatekeepers, they should only be running while the supervisor tasks are not working
- I2C module sending and receiving needs to be included in here somwhere. Inputs would be interrupt triggered.
- Task to check inbuilt preasure sensor every second and update GCS
- Task to write to a .klm for google earth to the SDCard every interval (interval is config parameter as is turning on this this logging feature. Check to see if SDCard is ok before writing, i.e. check it has not fallen out, check it is not full as well.
